Cooling things down could make London a friendlier capital

London Underground is crying out for air conditioning, and it would be a great opportunity to showcase design ingenuity.

The Tube is also such an iconic symbol of London, and this could enhance its status with a unique and artful system.

It would benefit everyone, not just Tube travellers – there’d be a knock-on effect. Londoners would no longer be grumpy after their journey into work, and I bet we would find brusque commuters would soon shed their blinkers and acknowledge each other’s presence once things cooled down a little.
